Casterly Rock

Casterly Rock

Casterly Rock is the ancestral home and stronghold of the Lannister family. Located on the western coast of Westeros by the Summer Sea, Casterly Rock is situated on an imposing promontory, looming above the city of Lannisport. This strategic location is one of the reasons the city has been implied to be impervious to a direct attack on the show.

It can be assumed that the majority of the Lannister's incredible wealth is stored at Casterly Rock. However, with their armies stationed in King's Landing and out in the field fighting Robb Stark, it is unclear what force may remain defending their ancestral stronghold.
